I know the question's been asked a million times. I've read and tried most solutions and haven't received a fix. I come from working on a Mac in Final Cut X, cutting a 30 minute TV show every week. I took the same footage over to Premiere CC 2015.3 on Windows and even just trying to play back a single clip with no effects the video preview lags behind the audio.
Just trying to play back a 1080p H.264 MPEG4 AVC QuickTime Video, 29.97 FPS. None of the following worked: Tried reducing playback quality to 1/4. Ensured the sequence settings matched my video settings. Rendered from in to out. Uninstalled the application and installed it again on my SSD alongside my OS. The footage is being played back from a separate internal HDD.
I really doubt it's a hardware problem because I'm running a 6700K @ 4.4GHz OC, 16GB DDR4 2400 RAM, Nvidia Gigabyte G1 Gaming 1070 card w/ up to date drivers.
EDIT: To start my project I'm creating new project with Mercury GPU (CUDA) renderer. Then rather than deal with settings I drop my main clip into the timeline and it auto detects the footage incorrectly, setting the FPS to 10fps. Changing this back to 29.97 does nothing. Even rendering it all out after this change doesn't change anything.
EDIT 2: Went and looked up the Premiere Pro CC course on Lynda, downloaded that project and media. Everything works great. So where's the issue? In my project settings or with the media?
Any final ideas? A NOOB guide on setting up the project and sequence in case I'm missing something? Thanks so much for your help. If I can't solve it in a week, I'll be asking for a refund from Adobe.
